Abstract (en)
[origin: US4762901A] A process is described for the preparation of polymeric networks having superstructures, resulting from the use of liquid-crystalline, (poly)functional units, characterized in that build-up into polymers is carried out by the polymerization, polyaddition or polycondensation process within the liquid-crystalline, preferably nematic, temperature range of the (poly)functional units, having a liquid-crystalline character, used for building up the networks. Polymeric networks which are accessible by this process, and the use thereof, are also claimed.
